摘　　要：对比传统FDM系统控制信道和业务信道均全向发射的特点,分析传统基站检测方法应用于TD-LTE基站检测时可能遇到的问题——辐射场强受基站业务量影响,测量值无法反映最大值或对其他频段的影响情况。提出对TD-LTE基站工作频段控制信道的实时值积分,根据控制信道与工作频段的带宽比例推至整个工作频段,进而得到基站的潜在最大辐射值的方法。通过测试实例,证明该方法在得到基站的潜在最大辐射值的同时,还可得到TD-LTE基站明确的工作频段,克服了上述问题。Compared to the traditional FDM system whose control channels and traffic channels were all omni-directional transmitting, the measurement methods used to a traditional base station may encounter some kind of problems： the radiation field depends on the traffic situation so that the testing value could not reflect the maximum value; the value of other bands may also impact the measurement of the TD-LTE base station. A method was proposed to get the potential maximum value of the base station, which first integrated the real-time value of control channel, then calculated the value of the entire operating band according to the bandwidth proportion. Through test cases, it was proved that this method could get the potential maximum value of the base station, meanwhile, give a clear working band, overcome upper problems.
